[catalogued under 27. Natural Reality / B. Modern Physics / 2. Electrodynamics / a. Electrodynamics]

Full Idea

Dirac created quantum electrodynamics (QED): the universal electro-magnetic field can exist in discreet states of energy (with photons appearing and disappearing by energy excitations. This combined classical ideas, quantum theory and special relativity.

Gist of Idea

In QED, electro-magnetism exists in quantum states, emitting and absorbing electrons

A Reaction

Close says this is the theory of everything in atomic structure, but not in nuclei (which needs QCD and QFD). So if there are lots of other 'fields' (e.g. gravitational, weak, strong, Higgs), how do they all fit together? Do they talk to one another?
